A technique based on the use of orthogonally-polarized pulses is proposed to mitigate the detrimental impact of modulation
instability on Brillouin distributed fiber sensors. While the theoretical underpinnings of the method are described by
introducing a detailed model for the vector modulation instability, the technique is experimentally validated in a 25-km
sensing link. Numerical and experimental results demonstrate that the use of orthogonally-polarized pulses not only
mitigates the impact of modulation instability, but also the four-wave mixing occurring in systems using pumps with
parallel polarization; thus, providing an important sensing range enhancement with a reduced pump depletion. [--]
